## LED drivers## CONFIG_LEDS_PCA9532 is not setCONFIG_LEDS_GPIO=noCONFIG_LEDS_GPIO_PLATFORM=no# CONFIG_LEDS_LP5521 is not set# CONFIG_LEDS_PCA955X is not set# CONFIG_LEDS_DAC124S085 is not set# CONFIG_LEDS_BD2802 is not set

## LED Triggers#CONFIG_LEDS_TRIGGERS=noCONFIG_LEDS_TRIGGER_HEARTBEAT=no# CONFIG_LEDS_TRIGGER_BACKLIGHT is not setCONFIG_LEDS_TRIGGER_DEFAULT_ON=no
